About Mark Mesko

I run the estimating, project management, quality control, and business development functions at Mesko Glass & Mirror Contracting Division, a commercial glazing subcontractor serving Northeast Pennsylvania for nearly 100 years.What that looks like in practice: I price Division 08 scopes, manage active jobs from award through closeout, maintain GC relationships across a large bid portfolio, and own quality assurance on everything we put in place.A few things I\'ve built from the ground up:Designed and implemented our quality control program, then led the company through NACC third-party certification — a process that required building custom safety plans, quality manuals, and field protocols from scratch.Integrated Hilti tools platform and OnTrack asset management across field operations, replacing a manual process that had no real tracking.Embedded AI tools (Claude AI) into daily workflows: custom prompts, scheduled automations, and operational systems that have meaningfully changed how the team estimates, manages projects, and handles administrative output.The numbers: 35% gross margins on managed projects. Backlog grew by $5M+. Estimate production up 3x. Branch turnaround from $100k net loss to $200k+ profit in 18 months.Finance BBA, Temple University Fox School. Proficient in Glazier Studio, Partner Pak, Foundations, and Microsoft Suite.
